"This work presents the most advanced discoveries from translational research laboratories directly involved in identifying molecules and signalling pathways that play an instrumental role in metastasis. In contrast to other works, conventionally focused on a single type of tumour, the various chapters in this book provide a broad perspective of the similarities and discrepancies among the dissemination of several solid malignancies. Through recurrent and overlapping references to molecular mechanisms and mediators, the readers will gain knowledge of the common ground in metastasis from a single source. Finally, an introductory chapter provides a clinical perspective of the problems presented by metastatic tumours for diagnosis and treatment. "

ABSTRACTIntroduction: The presence of breast cancer stem cells is considered to contribute to therapeutic resistance. There are some mechanisms affected therapy response in the cancer, such as active embryonic signaling pathways, inhibition of apoptosis and high DNA repair, adaptation to hypoxia and oxidative stress.Aim: to analyse the stemness gene expression profile in breast cancer after neoadjuvant chemotherapy and hormonal therapy correlated with apoptotic p53 , oxidative stress NFkB and hypoxia HIF- signaling pathways and also therapeutic responses.Methods: This study used breast tissue samples IIIB and IV before neoadjuvant therapy 46 pre samples and after neoadjuvant therapy 46 post samples . Total RNA was measured the expression profile using Next Generation Sequencing Truseq targeted RNA expression Illumina with stem cell, p53 and NFkB panels. In addition, HIF-1 and HIF-2 expression were measured using qRT-PCR. Results: After neoadjuvant therapy, the expression profiles of breast cancer genes that have good molecular responses in stem cells pathway are CCNE1, CDC42, CTNNB1, HDAC2, PSEN1, PSENEN, in apoptotic pathway are BIRC5, CASP8, CASP9, CDK1 and PCNA, in oxidative stress pathway are SOD2, STAT1 and TBK1, as well as in the hypoxic pathway HIF-1 and HIF-2 . Expression profiles with poor molecular responses in stem cells pathway are ALDH1A1, ALDH2, CCND2, CXCL12, FZD7, IGF1, while in apoptotic pathway are ATM and BID. Histopathologic response Miller Payne was significantly positively correlated with apoptotic pathway gene expression with good molecular response BIRC5, CASP8, CDK1 , but negatively significant correlated with ALDH1A1 gene expression. Survival of breast cancer patients significantly negatively correlated with ALDH1A1 and SOD2 expression.

"Latar belakang: Prediabetes didefinisikan sebagai keadaan hiperglikemia dengan kadar glukosa di atas normal dan dapat berkembang menjadi keadaan diabetes. Beberapa studi membuktikan keadaan defisiensi vitamin D berhubungan dengan keadaan resistensi insulin. Penelitian ini bertujuan untuk menganalisis efek modulasi suplementasi vitamin D terhadap mekanisme molekular pada kondisi resistensi insulin melaluli regulasi persinyalan jalur inflamasi dan mikrobiota usus pada tikus prediabetes.Metode: Penelitian ini dilakukan pada tahun 2019-2021 di Fakultas Kedokteran Universitas Indonesia dan Medica Satwa Laboratory Bogor. Eksperimen dilakukan pada tikus Wistar jantan berumur 4 minggu. Tikus akan dibagi secara acak, yaitu tikus yang menerima diet normal dan diet tinggi lemak dan tinggi glukosa (DTL-G)yang dikombinasi dengan dosis rendah injeksi streptozotocin 30 mg/kgBB intraperitoneal pada minggu ketiga. Setelah itu dilakukan tes toleransi glukosa oral (TTGO) dengan dosis 2 gram/kgBB pada tikus. Jika telah terjadi resistensi insulin (model tikus prediabetes) maka tikus prediabetes dibagi dalam tiga kelompok secara acak yaitu: (1) kelompok yang tidak diberi terapi, (2) kelompok yang diterapi vitamin D3 dosis 100 IU/kg/hari, (3) kelompok yang diterapi vitamin D3 dosis 1000 IU/kgBB/hari bersamaan dengan induksi DTL-G 12 minggu. Setelah itu akan dilakukan pengukuran kadar glukosa darah puasa (GDP), kadar glukosa darah 2 jam pasca-bebas glukosa, nilai HOMA-IR, kadar Glycated albumin, profil hematologi, kadar 25(OH)D3,pengamatan histopatologi pankreas, kadar TNF-alpha, IL-6, IL-10, NF-κB, TLR2, TLR4, PPARg, IRS1, dan komposisi mikrobiota usus.Hasil: Pada tikus prediabetes terjadi peningkatan nilai glukosa darah puasa, kadar glukosa darah 2 jam pasca-bebas glukosa, nilai HOMA-IR, kadar Glycated albumin, serta perubahan profil hematologi. Pemberian vitamin D 1000 IU mampu menurunkan nilai GDP, TTGO, Glycated albumin, HOMA-IR, serta mampu mengurangi degenerasi pada pulau Langerhans. Vitamin D 1000 IU mampu meningkatan sitokin anti-inflamasi IL-10, menurunkan ekspresi TLR2 dan TLR4, mengembalikan ekspresi IRS seperti kelompok normal, serta dapat meningkatkan keragaman mikrobiota. Suplementasi vitamin D berkorelasi dengan kadar PPARg, IRS1, TLR2, TLR4, dan sel beta pankreas.Kesimpulan: Pemberian vitamin D 1000 IU bersamaan dengan DTL-G pada tikus prediabetes dapat memberikan perbaikan kondisi resistensi insulin, meningkatkan sitokin anti-inflamasi, mengembalikan nilai ekspresi PPARg, meningkatkan ekspresi protein IRS1 kembali seperti kelompok normal, serta meningkatkan keragaman mikrobiota yang berkorelasi dengan regulasi persinyalan sitokin inflamasi.

Introduction: Prediabetes is defined as a state of intermediate hyperglycemia and can lead to type 2 diabetes. Several studies have shown that vitamin D deficiency is associated with insulin resistance. This study aimed to analyze the modulating effect of vitamin D supplementation on the molecular mechanisms of insulin resistance through signaling regulation pathways of inflammation and gut microbiota in prediabetic rats.

Methods: The study was conducted during 2019-2021 at the Faculty of Medicine, Universitas Indonesia and Medica Satwa Laboratory Bogor. The experiments was conducted on male Wistar rats of 4 weeks. Rats were divided randomly into control and a high-fat and high-glucose (HFD-G) diet combined with 30 mg/kg intraperitoneal injection of streptozotocin in the third week. Oral glucose tolerance test (OGTT) was performed at 2 grams/kgBW gluocose. If insulin resistance has occurred (prediabetic rat model) then rats were randomly divided into three groups, namely: (1) the group that was not given therapy, (2) the group with vitamin D3 at a dose of 100 IU/kgBW/day, (3) the group with vitamin D3 at a dose of 1000 IU/kgBW/day together with HFD-G in 12 weeks. Fasting blood glucose (FBG) levels, OGTT, HOMA-IR, Glycated albumin levels, hematological profiles, 25(OH)D3 levels, pancreatic histopathological observations, TNF-alpha, IL-6, IL-10, NF-B, TLR2, TLR4, PPARg, IRS1, and gut microbiota composition was evaluated.

Results: In prediabetic rats there was an increase in FBG, OGTT, HOMA-IR, Glycated albumin levels, and changes in hematological profiles. The administration of vitamin D 1000 IU could reduce the levels of FBG, OGTT, Glycated albumin, HOMA-IR, and could reduce degeneration of the islets of Langerhans. Vitamin D 1000 IU increased the anti-inflammatory cytokine IL-10, decreased the expression of TLR2 and TLR4, increased IRS1 expression like the normal group, and increased the diversity of gut microbiota. Vitamin D supplementation correlated with levels of PPARg, IRS1, TLR2, TLR4, and pancreatic beta cells.

Conclusion: Vitamin D 1000 IU vitamin D together with HFD-G in prediabetic rat could reduce insulin resistance, increased anti-inflammatory cytokines, increased PPARg expression level, increased IRS1 protein expression, and increased diversity of gut microbiota which correlates with signaling regulation of Inflammatory Pathways."
